Rapper Eminem is determined to prove he once had a relationship with Mariah Carey - he has threatened to release intimate photos and voicemail tapes from their affair in a shocking new song.

The Stan hit-maker sparked a war of words with the superstar earlier this year by hinting that he had slept with her in his track Bagpipes From Baghdad. The controversial song upset Carey and her husband Nick Cannon, who publicly criticized the rapper for his crude lyrics.

Carey went onto call Eminem "delusional" in her latest single Obsessed and dressed up as man in the video, with her male alias bearing a striking resemblance to the star. But Eminem has struck back, by releasing The Warning online.

The hip-hop star refers to Carey by name and threatens to expose their relationship in the press, claiming to have pictures of them together and taped phone calls she made to his house.

He raps, "Only reason I dissed you in the first place is because you denied seeing me. Now I'm p#*sed off. I'm obsessed now Oh gee, is that supposed to be me in the video with the goatee. B*@ch, shut the f*%ck up before I put all them phone calls out you made to my house. How many times you fly to my house? Still trying to count. Better shut your lying mouth if you don't want Nick finding out. You probably think since it's been so long if I had something on you I woulda (sic) did it by now. On the contrary, Mary Poppins, I'm mixing our studio session down and sending it to mastering to make it loud. Enough dirt on you to murder you. Mariah, it ever occur to you that I still have pictures?"

Eminem goes on to describe intimate details of their sexual exploits and dares the singer to deny the claims, "If I'm embarrassing me, I'm embarrassing you and don't you dare say it isn't true."

He asks Carey to stop denying their past, or he will go through with his threat to expose her as a liar: "Call my bluff and I'll release every f**king thing I got including the voicemails right before you flipped your top."

"It cuts like a (knife) when I tell ya (sic) get a (life). But I'm movin' on with mine. Nick, is that your wife. Well tell her to shut her mouth then I'll leave her alone. If she don't then I'ma (sic) just keep goin'."
